Abstract

A current driven flyback power supply has a transistor current switch which periodically couples a primary current through the primary winding of a power transformer which is connected between a source of DC and the collector of the current switch. A current transformer has a first winding coupled between the primary winding and the collector of the current switch, and a second winding which develops a drive current proportional to the primary current. The drive current is coupled to the base of the current switch and increases proportionally with the increasing amplitude of the primary current. An electrical switch shorts the drive current to ground to turn off the current switch so that stored energy in the power transformer is coupled out through its secondary winding to an output rectifier circuit which develops the output DC voltage. After the stored energy has been completely coupled out through the secondary winding, a first current pulse is developed to turn on the current switch to initiate the primary current. During high output power loading conditions, a second current pulse is developed at a selected point in time after the current switch turns off and prior to the stored energy being completely coupled out through the secondary winding. The second current pulse turns on the current switch whereby the initial primary current is boosted in amplitude by the residual stored energy in the power transformer.
